Polarization vortices generation by diffraction from a four quadrant polarization mask
In this work we analyze the generation of an array of polarization singularities (polarization vortices) in the diffracted field produced by a simple four quadrant polarization mask, which transmits two orthogonal linear states in different quadrants. We use the Jones matrix method to analyze the po...
